Bearing seat assembly, engine and vehicle

Abstract

The invention provides a bearing seat assembly, which includes an upper connecting seat and a lower connecting seat; the upper connecting seat is provided with a connecting cylinder for installing an OCV control valve, and an oil inlet passage and a control oil passage arranged inside the upper connecting seat and communicating with the connecting cylinder ; The lower connection seat is provided with an oil supply path connected to the oil inlet path. Through the structure of the connecting cylinder, the connection between the OCV control valve and the upper connection seat of the bearing seat is installed, and the control oil circuit is connected with the VVT ​​controller, and the oil inlet circuit is connected with the oil supply circuit in the lower connection seat to form a control circuit. Compared with the external design of OCV, the length of the oil passage is greatly shortened, the loss of oil pressure is reduced, the addition of auxiliary control valves and other related components is avoided, the cost problem is solved, and the problems in the existing engines using variable valve timing technology are solved. The OCV valve design has technical problems such as high system complexity and high equipment cost. The invention also provides an engine and a vehicle.

Description

technical field [0001] The present invention relates to the technical field of vehicle equipment, more specifically, to a bearing seat assembly, to an engine, and further to a vehicle. Background technique [0002] At present, VVT (Variable Valve Timing) technology has been widely used in the engine field. Its principle is to adjust the amount of intake (exhaust), valve opening and closing time, and angle according to the operating conditions of the engine so that the incoming The air volume is optimized to improve combustion efficiency, and its advantages are fuel saving and large power-to-liter ratio. [0003] In the existing designs, VVT engines are generally used, and the general OCV valve (oil control valve for intake valve timing) is arranged outside or in the middle of the engine body. However, there are corresponding design problems, specifically: [0004] When it is installed externally, the control oil circuit from OCV to VVT is longer, the pressure loss of the oi...
